| 9:05-10:05 | Invited Talk: Francesca Toni | From data and rules to argumentation frameworksArgumentation frameworks have been widely studied both in terms of formal properties they exhibit under di fferent semantics and in terms of applications they can support. But where are argumentation frameworks coming from, and how can argumentation, a model-based approach to AI, benefi cially integrate with the nowadays-much-widespread data-centric AI perspective? In this talk I will overview applications empowered by a variety of (extension-based and gradual) semantics for abstract and bipolar argumentation frameworks automatically obtained from data (including but not limited to text) and from logical rules. Some of these applications require the integration of argumentation and machine learning, and result in a mixed model-based and data-centric pipeline. For some applications, the semantics informs the defi nition of the frameworks rather than, as is conventionally the case, being enforced on frameworks a posteriori. | |
